Making a Web Mercator tile cache is easy nowadays, in FME this can be accomplished with a few well-chosen transformers. However, if one needs to generate a TC in another reference system, i.e. SWEREF99 TM (EPSG: 3006) that we Swedes hold so dear, it can be a bit trickier. The "Any EPSG Dynamic Tile Cache" concept is a way to approach these issues. The presentation will also cover how point clouds could be used to enhance performance when dealing with heavy datasets.

10. Engineering and design to shape a sustainable future
• Urbanisation, globalisation, digitalization and
climate change create new needs.
• New solutions need to be sustainable and based
on facts and data.
• We believe in the positive power of human
curiosity and the art of engineering and design
to achieve this.
• Tomorrow’s societies need an advisor with
recognized expertise.

coordinate systems
The Problem in Sweden..
Hmm… and all of those web tile
caches uses some international
standards

15. • More simple server
setup (no geoserver
or database)
• Fast loading in web
maps
Why (local) TileCache?
(NOT LOCAL..)

16. • TC origin coordinates
• Tile size in pixels.
• Tile spacing for each
zoom level

17. How it works
Hi! I’m a vector
(point) feature. My
coordinate is (25,25)
Cool!
• Each tile size is 256px
• In this zoom level, each
tile is 10m wide in ground
units.
That should put you...
Dataset
The Wizard.fmw
Feature

18. How it works
... In this tile, which is Row 3
and Column 3. Its a great tile!

19. How it works
The tile (3, 3) should have the extent
coordinates [20, 20, 30, 30]. I will use this
extent to get the necessary features from
the DB to create the PNG file.
I don't care...
Thanks for your help Mr Feature
